H2W introduces its latest high precision air bearing linear positioning stage (ABS-012-12-030-X). The ABS series stage incorporates five magnetically preloaded air bearings for both load carrying and lateral guidance. The base of stage is constructed using a lapped granite surface plate and the lateral guidance is controlled by a granite straight edge that is mounted to the base.
The non-contact 3 phase brushless linear motor operates in conjunction with a high resolution linear encoder for closed loop operation. The ironless core coil assembly has no magnetic attractive force to the stationary magnet assembly, and as a result it does not induce any cogging into the system. The lower moving mass of the stage allows for much higher accelerations of light payloads.
The stage has a stroke of 12 in [300 mm]; generates 20 lbs [89 N] of continuous force and 60 lbs [267 N] of peak force. It includes a 1 micron resolution linear encoder.
H2W’s line of air bearing positioning stages are ideal for high precision applications requiring extremely flat and straight, non-contact motion.
Features:
- Non-contact air bearing operation
- Excellent flatness and straightness specifications
